ESXi 3.5 into 4 upgrade problem in adding Existing VMFS partition on iSCSI SAN
I've got 2x Dell PowerEdge 2950-III directly attached with Dell MD3000i iSCSI-SAN and today I had a hard times in upgrading my production ESXi 3.5 u 4 into ESXi 4.0,
First is that the upgrade is failed miserably after following this thread: VMware Communities: error on host upgrade: this host is not compatible with this upgrade.
with the following Error message: ERROR: Unsupported boot disk
The boot device layout on the host does not support upgrade.
therefore I did a clean reinstall of ESXi 4 on top of ESXi 3.5 u 4 and lost every single settings on my ESXi host.
I'm now stuck in mapping the iSCSI SAN partition after following the guide from: http://support.dell.com/support/edoc...rage_guide.pdf
see the following attachment.
I wonder how does people do their upgrade into ESXi 4.0 in production system that is running ESXi 3.5 u 4 filled with hundreds of VM ?
The reason why I'm using 2x ESXi server connected into single SAN server is that I can just start the VM on the SAN from the other ESXi --> which is fine and tested, but then when i rebuild the failed server, I must delete the whole data inside the shared partition which contains my VMs.
So in conclusion after one of the ESXi Server failed, the iSCSI mapping would eventually destroy every single data in the partition ?
any idea and suggestion would be gladly appreciated
